"I’m open to changing the law if it’s not working, 'cause I think it's really important that we have integrity and transparency in our public services," Ms Bennett told 1 NEWS.

An investigation by the State Services Commission found that staff at the Ministry of Transport were worried about the repercussions of speaking out against ex-colleague Joanne Harrison.

Harrison is jailed for three-and-a-half years for stealing $726,000.

State Services Commissioner Peter Hughes says Harrison was a high manipulative individual who wreaked havoc within the ministry.

Now he wants the Government to review the Protected Disclosure Act.

"We need to update the act to make it more user friendly for people making disclosures and introduce proper reporting and monitoring requirements," Mr Hughes said.

Ms Bennett has asked for more information about what impact the changes would have.

"People that want to speak up about the behaviour that they do not think is legal or right should be able to do that and do that safely," Ms Bennett said.

"I'll do whatever I can to protect them."
